Proton.me vs Mailbox.org vs Posteo.de
Which one do you recommend for #email , calendar and address book? and Why? I need to use it with thunderbird on linux and lineageOS.

For that mix I’d decide on the boring compatibility pieces first: Thunderbird IMAP/SMTP, CalDAV/CardDAV, custom domain support if you need it, and export paths if you leave later.

Posteo is usually the “simple, privacy-minded personal mailbox” choice. Mailbox.org is better if you want a fuller groupware setup. Proton is strongest if you are mostly inside its own apps, but I’d test the Bridge workflow carefully before choosing it for Thunderbird + Linux + LineageOS.

@privacyfish yes, Thank you for the good advice. I have already decided exactly based on those.
@bsh Glad it helped. That compatibility-first check saves a lot of pain with email providers, especially when Thunderbird and mobile sync are part of the daily workflow.
